SRAM Chip Sync Dual 3.3V 4M-Bit 256K x 18 6.5ns 100-Pin TQFP Tray
The CY7C1325G is a 256 K × 18 synchronous cache RAM designed to interface with high speed microprocessors with minimum glue logic. Maximum access delay from clock rise is 6.5 ns (133 MHz version). A 2 bit on-chip counter captures the first address in a burst and increments the address automatically for the rest of the burst access. All synchronous inputs are gated by registers controlled by a positive-edge-triggered Clock Input (CLK).
